JohnB is on a distinguished road
I have removed and replaced a similar model on one of my 2004's. If you are doing a total pull and replace, it is not that hard but I do not know your background skills.

The outside flange is sealed to the side of the camper like any door, window or cargo hole that uses putty tape. You will need new sealing tape when you put it back on.

You will have to deal with the gas line and that fitting can be hard to get at and threaded back on true. You have to do a gas leak test after you install it.

The electrical part of hook up is not that bad. There is power and a T stat connection

The duct hoses have a twist on flange adapter that goes from hose to the furnace round hole.

The hardest part is separating the seal to the side of the camper and the LP gas line connection due to the spot it is located in. hard to get to.

Hope this helps

Thanks for the info. Will keep it in mind, when I can get to it. Looks like life has thrown me another curve ball. That will put this project off some.

I may get back to you, with more questions, when I get to it.

Thanks again
